Air pollution is the introduction into the atmosphere of chemicals, particulates, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment. A substance in the air that can be harmful to humans and the environment is known as an air pollutant.
Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants can be classified as primary or secondary. Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulphur dioxide released from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact.
The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems .Pure air is always needed for inhaling. If we take pure air, our health improves.
On the other hand impure air causes diseases and impairs our health and causes our death. Smoke pollutes the air. It is the root of air pollution. There are four major reasons of air pollution emissions from vehicles, thermal power plants, industries and refineries. The problem of indoor air pollution in rural areas and urban slums has increased.
The smoke which is discharged from industries, automobiles and kitchens is the mixture of carbon monoxide, carbon dioxide, methane etc. These are all poisonous gases. These cause lung-cancer, tuberculosis etc. which take a heavy loss of life. Fine particles or microscopic dust from coal or wood fires and unfiltered diesel engines are rated as one of the most lethal forms or air pollution caused by industry, transport, household heating, cooking and ageing coal or oil-fired power stations.
During air pollution chemicals and particulates are release into the atmosphere. Common gaseous pollutants include carbon monoxide, sulphur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smogare created as nitrogen oxides and hydrocarbons react to sunlight. Particulate matter or fine dust is characterized by their micro-meter size.
Among the study’s finds were that retrofitted CNG car engines emit 30% more methane than original CNG engines. Almost all CNG car engines in India are retrofitted. Air quality is worst in Metro cities like Kolkata, Delhi, Mumbai, Chennai, etc.
Air pollution
You can’t escape from it. Everybody has to breath, and when air isn’t clean you health is affected. Air pollution is problem of all of us. You might think that you are healthy because you eat, and do only healthy things, so you cannot be sick, or get cancer, allergies or even die. Everybody is affected by air pollution.
At the first, what is air pollution? The air pollution is contamination of air by the discharge of harmful substances. We’ve got many pollutants, which cause air pollution. Like carbon monoxide, carbon dioxide, chlorofluorocarbons, lead and many more. All of these pollutants can cause lot of illnesses, like cancer, birth defects, brain and nerve damage.
Other pollutant from cars was lead; it is highly toxic metal. Lead has been phased out of gasoline, but there, are other sources of it. It includes paints, production of lead batteries, water pipes, and a few heir dye products. Car exhausts can also produce nitrogen oxide, volatile organic compounds, which are also, product of burning fuels. Factories and power plants produce same pollutants as cars do, but they produce them in bigger mnozstve and the produce some more such as sulfur dioxide, which is made during production of paper, burning coal in power plants, or smelting of metal. Burning other fuels like wood, or natural gas can make all of these pollutants too.
The other problem closely related to industrialization is problem of big cities. The problem of air pollution increases in the bigger cities because mnozstvo of cars, buses, and trucks. During the traffic jams all kind of pollutants are released into the air, and then people who live near roads have to breath this “dirty” air.
We use all kinds of chemicals that are damaging our air. Sprays containing chlorofluorocarbons damaging ozone layer in very top part of out atmosphere. Pesticide and other chemicals use for protecting some plant might protect plants, but they are not helping to our air at all.
